now i'm a guy,

but i think it's weird as fuck for a guy to shave his own balls. it would just look unnatural, and the idea of using a razor on your balls is silly, i think.
that said, you definitely should NOT leave it as it is. you need to do something.

trimming is the most acceptable thing. shaving is better than leaving it.
it's pretty annoying to use scissors on your actual balls, but deal with it and be careful not to cut yourself.
